Fertilization principle Winter melon is suitable for growth in sandy soil rich in organic matter, resistant to fertilizer and inferior, and requires comprehensive nutrients such as nitrogen, phosphorus, potassium and calcium. The base fertilizer should be reapplied and the fertilizer should be properly applied. In the seedling stage, the nutrient absorption is small, and the convulsion period is more, while the flowering result period, especially in the early and middle stages of fruit development, is the most, and gradually decreases in the later stage. Increased nitrogen fertilizer, longer main stem, increased application of phosphorus and potassium fertilizer, can delay the aging of early maturing varieties, and can reduce the female flower node and increase the weight of single melon.
Base fertilizer Winter melon should be applied to the base fertilizer, generally 300-500 kg of refined organic fertilizer per acre; if using homemade organic fertilizer, the organic fertilizer should be fully decomposed, and increase the dosage, 3000-5000 kg per acre. At the same time, organic fertilizer should be applied with phosphate fertilizer and potassium fertilizer. Apply 20 kg of diammonium phosphate and potassium chloride per acre. Phosphate fertilizer should be mixed with organic fertilizer and applied together.
After top dressing, 8 kg of ammonium sulphate or 3 kg of urea is applied per acre. After sitting on the melon, 15 kg of urea and 20 kg of potassium sulfate were applied per mu. In the future, apply 10 kg of diammonium phosphate per acre for 1 to 2 times.
